LP87561-Q1: Question about EN control logic

Part Number: LP87561-Q1

Hi team,

We want to make sure that some question about LP8756X-Q1.

1、Can any enable PIN control any Buck?
2、Is the software configuration firmware? Do I need to reconfigure the registers every time when the LP8756 is given power up? Or do we just need to configure it first time and then no more configuration?

    Hi,

    1. Any enable pin which is configured as enable function can be used to control any buck.
    2. The registers are configured by one time programming (OTP) when NRST is asserted. If you want different settings than the OTP, the registers will need to be rewritten every time NRST is asserted.

    Thanks,
